2 Claims.

This invention relates to paper containers of the type wherein the body member of the container is of tubular formation consisting of a plurality of layers of paper wound in spiral formation. Such containers are today manufactured in large volume and wherein the tubular body member consists of one or more layers of relatively thick or heavy paper and an inner liner formed of two or more layers of relatively thin impervious material such as processed paper, or parchment, to render the-side wall of the container impervious for certain products, particularly those of an unctuous nature.

In addition to the inner liner layer of parchment, the container is rendered more or less impervious by the coating of glue or adhesive between the respective layers making up the side wall of thecontainer. Due to the possibility of the liner having small perforations which permit the contents of the container to seep into the outer layers of the body member, particularly through theseam or joint of the outer layers, it is customary to form the liner of two or more layers of parchment with the seam of one layer arranged-remote from the seam of the other. all whereby there are at least two layers of parchment or lining material extending throughout the length of the container in order to have a double thickness of the lining material covering the seam or joint of the inner layer of heavier "paper making up the side wall member. The

cost of this specially processed lining material adds materially to the cost of the container, and the employment of two or more layers throughout the entire length of the container makes this construction prohibitive in many instances.

rigidity and stifl'ness to the container. The layers II. II are so wound that the joint or scam I! of the inner layer II is arrangedsubstantlally midway between the seams or joints ll of the outer layer II, as is conventional in the tub winding art.

The inner liner I4 is formed or relatively thi sheet" material which is impervious to the products for which the container is intended to be used. This material may'be metallic foil, but in many instances parchment will serve the purpose. The web or strip forming the liner I4 is of ap-, preciable greater width than the strip forming the inner layer II, and the liner is so wound that the adjacent edges II, It thereof are arranged in overlapping relation, as distinguished from the abutting relation in the case of the outer layers II, ii, and with this overlap arliner ply is only for a relatively short distance This invention has as an object a container of the type referred to embodying a construction wherein only a single layer of lining material is employed, but is so wound as to provide a double thickness of lining material'over the sectional view of a container embodying my invention.'

The laminated body member is here shown as being made up of outer and inner layers II, II of relatively thick paper-board to provide proper and thereby eiiects a substantial saving in this material in comparison with previous containers in which the double ply lining material extends throughout the length of the container.

It will be understood that the various layers or plies are coated with a suitable glue or adhesive during the winding process, whereby the outer layers II, II .are securely bound together, and the liner iayen i4 is securely bound to the layer II, and that the overlapping portions it, it are in like manner pasted together.

What I claim is:

1. A tubular container having a side wall formed of a plurality of spirally wound layers of fibrous material adhesively secured together and a single inner layer of thin impervious material spirally wound, with the adjacent edges thereof arranged in overlapping relation, and said overlap being arranged in register with and overlapping the seam of the inner layer'of fibrous material. 7

2. A tubular container having a side wall formed of a spirally wound outer ply of fibrous material and an inner ply of thin impervious inateriai spirally wound with the adjacent edges of said inner ply arranged in overlapping relation, and said overlap being arranged in register with and overlapping the seam of said outer ply.
